EPDM air diffuser for domestic wastewater treatment

Product Description

Introduction:

EPDM air diffuser for domestic wastewater treatment, which is used to transfer air and with that oxygen into sewage or industrial wastewater. Oxygen is required by microorganisms in the water to break down the pollutants. Fine bubble diffusers produce a plethora of very small air bubbles which rise slowly from the floor of a wastewater treatment plant or sewage treatment plant aeration tank and provide substantial and efficient mass transfer of oxygen to the water. The oxygen, combined with the food source, sewage, allows the bacteria to produce enzymes which help break down the waste so that it can settle in the secondary clarifiers or be filtered by membranes.

Characteristic:

1. Use imported material, good elasticity, long life time
2. Little bubble diameter, high oxygenate efficiency
3. Proof deposit,install convenient

Technical Parameter:

Membrane material: EPDM/silicone/NBR
Plastic Tray material: ABS/UPVC/PP
